* Add simple browser extension
This change adds a new 'simple browser' extension. This extension uses a webview to render webpages directly in VS Code. We plan on using it for optionally previewing local servers in both desktop and codespaces
The browser itself has a number of limitations due to the security around iframes:
- It traps keyboard focus
- We can't detect if a page fails to load
- We can't track the current url of the iframe
* Add experimental alert when the iframe is focused
* Disable events on focus warning
* Hooking up simple browser to opener
